Ni-coated Si electrodes for water splitting

http://news.stanford.edu/news/2013/november/nickel-water-splitter-111213.html

Thin film (~2 nm) Ni coated on Si electrode to prevent Si corrosion when splitting water.  Good performance over 3 days without corrosion.  Li-ion addition to electrolyte solution (instead or in addition (?) to KBO3) increases stability of the electrodes.
